Fan attachment for sewing-machines

FAN ATTACHMENT FOR SEWING-MACHINES.

Specification forming part of Letters Patent N o. 53,158, dated March13, 18,66.

To all whom it may concern:

Be it known that I, THOMAS R. LOVETT, of Mount Airy, in the city andcounty of Philadelphia and State of Pennsylvania, have invented a newand Improved Fan Attachment l to SewingMaehines; and I do hereby declarethat the following is a full, clear, and exact description thereof,which will ena-ble others l skilled in the art to make and use the same,reference heilig' had to the accompanying drawl ings, forming a part ofthis specilication, in l whichf Figure l is a front elevation of myinvention. Fig. 2 is af sectional View, the plane of section being takenon the line .fr :0, Fig: l.

Si milarletters of referenceindicatelike parts.

This invention relates to a ditferent manner ot' operating a fanattachment to a sewing-machine to that patented to me November 2l, 1865.

The nature of this invention consists in the l means employed fortransmitting motion from the shaft-ot' the driving-Wheel of the machineto the fan for keeping the latter in motion to effect an agitation ofthe air around the operator for keeping him cool while operating themachine, suitable machinery being employed for throwing the parts out ofgear so thatthe fan will remain at rest when desired.

A designates the table of a sewing-machine, and B its legs. O is thedriving-wheel mounted on its shaft O', all constructed and arranged inthe usual manner.

D is a standard attached to the back edge of the table Ain any suitableway. To the top of this standard bearing blocks or pieces a alareattached, through which a shaft, b, passes. One end of this shaftcarries a revolving fan, E, and the other a pulley, c,- and to the lowerend of the standard O, in suitable guide-pieces f, two more pulleys, cc, are journaled. A

F is an endless cord or belt, which passes l by Letters Patent, is-

over the pulley c and under the pulleys c c and around the shaft of thedriving-wheel, (or over a pulley, z, on the shaft, as shown in thedrawings,) as shown clearly in Fig. 2.

Thus it will be seen that a rotary motion will4 be imparted to the fanby reason of the belt E passing over the shaft and the pulleys o c c andthe shaft O.

The guides j', in which the pulleys c c are mounted, is pivoted to thestandard D, so that its lower end can be thrown outward or drawn towardthe table, as desired, and a wedgeshaped slide, g, is arranged on thefront of the standard D, by pushing which downward throws the bottom ofthe guidefoutward,and by drawing which up allows it to approach thetable. By these means the cord can be tightened to communicate motion tothe fan or loosened to allow the fan to remain at rest, as occasion mayrequire.

By this simple arrangement a fan attached to a sewing-machinecan beoperated directly by the shaft of the machine, and a constant agitationof the air around the operatorbe effected, and the fann'ing may becontinuously kept up, and thus the operator can be kept cool in sultryweather while sitting at work.

What l claim as new, and

l. Operating a fan attachment to a sewingmachine by the driving-shaft ofthe machine through the medium of a belt, F, passing over pulleys o c cand the shaft O ofthe machine, substantially as described.

2. The guide f and wedge-slide g for throwing the belt F into or out ofoperation, in combination with the standard D and shaft C',substantially as specified.

THOS. B. LOVETT.
